MIXTURE REGULATION FOR FUEL-INJECTION OTTO MOTORS WITH THE LAMBDA PROBE

In regulating the mixture composition in otto motors with the lambda probe, the exhaust gas composition is monitored continuously by the probe which then controls the amount of fuel injected in such a manner that a catalyzer fitted in the exhaust system can effect the optimum reduction of all three pollutants - carbon monoxide, hydro-carbons and nitrogen oxides. The driving characteristics and fuel consumption of the vehicle are not impaired. (TRRL)
